OpenCV 环境搭建

OpenCV C++ 环境搭建

下载编译好的包

https://sourceforge.net/projects/opencvlibrary/files/4.1.1/

https://sourceforge.net/projects/opencvlibrary/files/4.1.1/opencv-4.1.1-vc14_vc15.exe/download

安装

双击opencv-4.1.1-vc14_vc15.exe 解压build 和 source并设置环境变量

Path：
d:\opencv\build
d:\opencv\build\x64\vc15\bin

新建OpenCV工程

#include<opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
     Mat img = imread("C://Users//26818//Desktop//1.jpg", IMREAD_GRAYSCALE); //载入图像到Mat
     if (img.empty()) // Check for invalid input
     {
         cout << "Could not open or find the image" << std::endl;
         return -1;
     }
     imshow("图片", img);
     waitKey(0);
     return 0;
}

配置项目属性页

VC++目录 包含目录：
C:\opencv\build\include
C:\opencv\build\include\opencv
C:\opencv\build\include\opencv2

VC++目录 库目录：
C:\opencv\build\x64\vc14\lib

链接器->输入-> 附加依赖项：debug 用opencv_world345d.lib， release用opencv_world345.lib

OpenCV Python 环境搭建

pip install numpy Matplotlib

pip install opencv-python

安装完成之后：使用 import cv2 即可
